Quick quiz almost refurbished laptop?

Is it a gaming laptop? If truthful, then that's normal. Diversion laptops require more power and waste more power due to the high powered internal components. If it's a standard laptop, then check the original battery life expectancy and if it's lower than that, then look into replacing it with an OEM battery.

Edit: To the typeguy... Refurbished and Used are two different matters. Research formerly you bring in erroneous statements.
